Arachnoid cysts do not contain cerebrospinal fluid: A comparative chemical analysis of arachnoid cyst fluid and cerebrospinal fluid in adults
(BioMed Central, 20100610)Background Arachnoid cyst (AC) fluid has not previously been compared with cerebrospinal fluid (CSF) from the same patient. ACs are commonly referred to as containing "CSFlike fluid". The objective of this study was to ...Journal articlePeer reviewed 
Bridging the ensemble Kalman filter and particle filters: the adaptive Gaussian mixture filter
(Springer, 2010)The nonlinear filtering problem occurs in many scientific areas. Sequential Monte Carlo solutions with the correct asymptotic behavior such as particle filters exist, but they are computationally too expensive when working ...Peer reviewedJournal article 
Brill–Noether theory of squarefree modules supported on a graph
(Elsevier, 201305)We investigate the analogy between squarefree Cohen Macaulay modules supported on a graph and line bundles on a curve. We prove a Riemann–Roch theorem, we study the Jacobian and gonality of a graph, and we prove ...Journal articlePeer reviewed 
A Continuous MaxFlow Approach to Minimal Partitions with Label Cost Prior
(The authors, 2011)This paper investigates a convex relaxation approach for minimum description length (MDL) based image partitioning or labeling, which proposes an energy functional regularized by the spatial smoothness prior joint with ...ChapterPeer reviewed 
Early prediction of response to radiotherapy and androgendeprivation therapy in prostate cancer by repeated functional MRI: a preclinical study
(BioMed Central, 20110608)Background: In modern cancer medicine, morphological magnetic resonance imaging (MRI) is routinely used in diagnostics, treatment planning and assessment of therapeutic efficacy. During the past decade, functional ...Peer reviewedJournal article 
Efficient Global Minimization for the Multiphase ChanVese Model of Image Segmentation
(Springer Verlag, 2009)The MumfordShah model is an important variational image segmentation model. A popular multiphase level set approach, the ChanVese model, was developed as a numerical realization by representing the phases by several ...Peer reviewedJournal article 
Feasibility of simplified integral equation modeling of lowfrequency marine CSEM with a resistive target
(Society of Exploration Geophysicists, 2009)We have assessed the accuracy of a simplified integral equation (SIE) modeling approach for marine controlledsource electromagnetics (CSEM) with low applied frequencies and a resistive target. The most computationally ...Peer reviewedJournal article 
Generating function and volume preserving mappings
(The American Institute of Mathematical Sciences, 201403)In this paper, we study generating forms and generating functions for volume preserving mappings in Rn. We derive some parametric classes of volume preserving numerical schemes for divergence free vector fields. In passing, ...Peer reviewed 
Genotyping errors in a calibrated DNA register: implications for identification of individuals
(BioMed Central, 20110420)Background: The use of DNA methods for the identification and management of natural resources is gaining importance. In the future, it is likely that DNA registers will play an increasing role in this development. Microsatellite ...Peer reviewedJournal article 
Global Minimization for Continuous Multiphase Partitioning Problems Using a Dual Approach
(Springer Verlag, 2010)This paper is devoted to the optimization problem of continuous multipartitioning, or multilabeling, which is based on a convex relaxation of the continuous Potts model. In contrast to previous efforts, which are ...Peer reviewedJournal article 
Histological type and grade of breast cancer tumors by parity, age at birth, and time since birth: a registerbased study in Norway
(BioMed Central, 20100521)Background Some studies have indicated that reproductive factors affect the risk of histological types of breast cancer differently. The longterm protective effect of a childbirth is preceded by a shortterm adverse ...Peer reviewedJournal article 
Liposomal doxorubicin improves radiotherapy response in hypoxic prostate cancer xenografts
(BioMed Central, 20111007)Background: Tumor vasculature frequently fails to supply sufficient levels of oxygen to tumor tissue resulting in radioresistant hypoxic tumors. To improve therapeutic outcome radiotherapy (RT) may be combined with ...Peer reviewedJournal article 
Modified action and differential operators on the 3D subRiemannian sphere
(International Press, 201012)Our main aim is to present a geometrically meaningful formula for the fundamental solutions to a second order subelliptic differential equation and to the heat equation associated with a subelliptic operator in the ...Peer reviewedJournal article 
Multiscale mass conservative domain decomposition preconditioners for elliptic problems on irregular grids
(Springer, 201106)Multiscale methods can in many cases be viewed as special types of domain decomposition preconditioners. The localisation approximations introduced within the multiscale framework are dependent upon both the heterogeneity ...Journal articlePeer reviewed 
New examples of curves with a onedimensional family of pencils of minimal degree
(Springer, 20110714)We give a geometric construction of sublinear systems on a K3 surface consisting of smooth curves C with infinitely many g1 gon(C)’s.Peer reviewedJournal article 
Numerical Modeling of Supercritical ‘OutSalting’ in the “Atlantis II Deep” (Red Sea) Hydrothermal System
(Bentham Open, 2007)Supercritical water behaves close to that of a nonpolar fluid and its ability to dissolve salt ions is very low. In rifting locations worldwide, where hot vents occur, it has been shown that seawater attains supercritical ...Peer reviewedJournal article 
Numerical modelling of organic waste dispersion from fjord located fish farms
(Springer, 20110421)In this study, a threedimensional particle tracking model coupled to a terrain following ocean model is used to investigate the dispersion and the deposition of fish farm particulate matter (uneaten food and fish ...Peer reviewedJournal article 
Numerical Simulation Studies of the Longterm Evolution of a CO2 Plume in a Saline Aquifer with a Sloping Caprock
(Springer, 20110202)We have used the TOUGH2MP/ECO2N code to perform numerical simulation studies of the longterm behavior of CO2 stored in an aquifer with a sloping caprock. This problem is of great practical interest, and is very challenging ...Peer reviewedJournal article 
On Semiimplicit Splitting Schemes for the Beltrami Color Image Filtering
(Springer, 2011)The Beltrami flow is an efficient nonlinear filter, that was shown to be effective for color image processing. The corresponding anisotropic diffusion operator strongly couples the spectral components. Usually, this flow ...Peer reviewedJournal article
